Hp dv5 amd sometimes shutdown

[MDY]

Hi,

I have a HP DV5 AMD. Problem is that sometimes (1 times each 1 runs) it shutdown after 5,6 seg.

Ejamples: I press power button, it run and shutdown after 5,6 seg.
I press power button again and it run and load windows and work good for hours.
I shut it down and run again and it shutdown after 5,6 seg.
I power again and it work good. When it run and past 5,6 seg. it work perfectly. Temperature is OK. Every 20 times run it, 1,2 times it shutdown after 5,6 seg. Any idea where to look for the problem?

As I said in my first post it is not temperature issue. I have clean laptop inside and put new thermal pad to GPU and CPU, and also it works for hours perfectly it it start up and pass first 6 seg.

try to clean the board w/ ultra sonic cleaner, could be contact problem

if the problem persist, change the rtc battery and update bios.

ultra sonic cleaner I have is only for BGA. There is ultra sonic cleaner for big motherboard? Or you do it another way?

You can use EDS brush if you have or tooth brush with isopropyl alcohol 99%.
